This Working Draft specification<http://www.w3.org/TR/html-aria/>; defines the web developer rules (author conformance requirements) for the use of [wai-aria-1.1] attributes on [HTML51] elements. It also defines requirements for Conformance Checking tools.

Web developers MAY use the ARIA role and aria-* attributes on HTML elements<http://www.w3.org/TR/html/index.html#elements-1>;, in accordance with the requirements described in [wai-aria-1.1<http://www.w3.org/TR/html-aria/#bib-wai-aria-1.1>;], except where these conflict with the strong native semantics<http://www.w3.org/TR/html/infrastructure.html#strong-native-semantics>; or are equal to the default implicit ARIA semantics<http://www.w3.org/TR/html/infrastructure.html#default-implicit-aria-semantics>; of a given HTML element. These constraints, are intended to prevent developers from making assistive technology products report nonsensical user interface information (UI) that does not represent the actual UI of the document.

Web developers MUST NOT use the ARIA role and aria-* attributes in a manner that conflicts with the semantics described in the Document conformance requirements for use of ARIA attributes in HTML<http://www.w3.org/TR/html-aria/#docconformance>; table. Web developers SHOULD NOT set the ARIA role and aria-* attributes to values that match the default implicit ARIA semantics defined in the table.
